Abstract:

The quicksand state of the Northern soils in thawed form, and the high ice content of certain levels of them in frozen condition is associated to a significant extent with the hydrophilic nature of the humus of these soils. In a survey of the seasonal freezing of the soils by zones, one can in no event overlook also the zonality of their ice state, depending to a known extent on the colloidal chemical nature of the humus of the given soils.
